To all whom, t uta/y concern: 'L

Be it known that l, HENRY APPLER, a citizen of the United States,residing at St. Louis, Missouri, have invented a certain new and usefulVImprovement in Vehicle-Brakes, of which the following is a full, clear,and exact description, such as .Will enable others skilled in the art toWhich it appertains vto make and use the same, reference being had tothe accompanying drawings, formingpart of this specification, in which-e77 ofFig. 2.

My invention relates to improvements in vehicle-brakes, the presentbrake 4being de l signed more particularly for use upon railway-cars.

My object is topprovide a brake by means of which a car can be quicklystopped, the wheels being lifted from the track and permitted to rotatefreely.

A further object is to combine with the mechanismjust described means.whereby the wheel itself can be braked.

To these ends and also to improve generally upon devices of thecharacter indicated my invention consists in the various mattershereinafter described and claimed. l

In the accompanying drawings I have shown the invention applied tocarailway-car.

Referring now more particularly to ,the drawings, l represents .theusual caraxle, mounted upon a suitable truck 2, andB indicates a WheelVmounted upon the said axle in any convenient manner. -Pivotallysupported upon the axle and in. rear` of the Wheel is adetentnotches 9at diametrically opposite Y points.

Extending about the axle is a cylindrical casing 10, and formed uponthis casing or otherwise suitably connected to the inner end thereof areplates ll, Which engage and slide vertically upon vertical guide-posts13, which depend from a horizontal bar 14, suitably supported upon tlieWheel truck. Mounted in said casing to slide horizontally is a lockingbar or bolt l5, which is adapted to cooperate with the Yrecesses 9 inthe liftingplate, said bar beingnormally held in projected position bymeans of a leaf-spring 16, Whose action is supplemented by a coiledspring 17, interposed between said leaf-spring and the inner head of the'said casing.,-

Splined upon the axle is lafsleeve 18, VWhose forward end is providedwith teeth 19, adapted to cooperate with the teeth upon the liftingplatein'order to form connection between the said sleeve'and plate. A'yokeQO,suitably pivoted to the casinglO', has arms provided Withinyvardlyfprojecting fingers 2l which enter a peripheral recess 22 inthe said sleeve, and a reducedportion 23 ofthe locking-bar l5 isreceived in the slot between upwardly-extending fingers 2i upon thesaidyoke, the saidfiingers 24 and the Yfingers 21 being upon opposite sidesof thefpivotal point of the said yoke. The bar l5 has shoulders 25,which lie upon opposite sides of the iin' gers 2d, and movement of thesaid bar therefore serves to rock the said yoke.

The locking-bar l5 if so connected to some suitable lever or othermember 26 upon the car or under the control of the trainmen that the barcan be operated from the car or train. This connection can be effectedin many ways, and I have here shown a shaft 27 extending longitudinallybeneath'the car and rotatably supported in any suitable manner, saidshaft having connection by gears or otherwise with avertical shaft 28,which is in turn connected by beveled gears to a' horizontal shaft 29within the car, the ,leverv 26 extending vertically from saidlast-mentioned shaft. The levers 26 in several cars Vconstituting atrain can be conveniently connected by an operating-cord 30, so that thedevice can be operated from any part of any car of the train. Arms 31extend radially from the longitudinal shaft 27, and these arms arepivotally connected to the locking-bars 15. It will of course beunderstood that preferably each' wheel of a car is provided with alifting-plate and the other mechanism heretofore described. The arms'`31 are therefore arranged in pairs, the arms of a pair extendinguponopposite sides of thel shaft 27, so that as the shaft is rocked inone sition by the locking-bars 15, the bars being Vtherefore inprojected position and the shifting yokes 20 thus being held, so thatthe sleeves 18 are retracted and the teeth 19 are out of engagement withthe teeth 7. Each of the said sleeves can thusrotate with the axlewithout producing any effect upon the particular lifting-plate withwhich it is intended to operate. Whenit is desired' to stop the train,the shaft 27 is rocked, thus retracting the locking-bolts fromengagement with the various lifting-plates audthrowing the sleeves 18into operative connection with the said plates. Under these conditionsthe rotation of an axle serves to carry the lifting-plates with it.

vThe operating cord or lever is released almost as soon as pulled, sothat the lockingbolts are forced by their springs against the ribs 8,the teeth 7 and 19 being in interengagement when the said bolts abutagainst said ribs, and as soon as the lifting-plates have made half arevolution the bolts are shot into the proper recesses 9 for lockingthe4 plates in lowered position, the sleeves 18 being retractedsimultaneously with such movement of the bolts. The ends of the flange 5of a locking-plate lie close to the tread of the wheel, so that as saidlocking-plate is turned its fiange engages the tread of the rail withoutshock and the car is gradually lifted to carry its wheel above thetrack, andas the liftingplate is locked in its new position anon-rotatable member rests upon the track and the wheels are left freeto rotate. The treadiiange of each lifting-plate is provided with aflange 31, adapted to rest upon the inner side of the rail, and thusprevent derailment of the car.

Each lifting-plate is preferably provided with wedging-blocks, soarranged that such a block is thrown under the plate and wedged betweenthe plate and the track in order to facilitate rapid stopping of thetrain. At its centralpoint-that is, the point adapted to rest upon therail when the plate is thrown into operative position-the lifting-plateis provided in its periphery with arecess 32, which extends across thetread-fiange 5, and a recess 33, extending across the said flange, isprovided in the periphery of the flange upon each side of the saidrecess 32. Wedge-blocks 34 normally lie in the said recesses 33, saidblocks having their inner faces inclined away from the central point ofthe periphery of the'lifting-plate and away from the periphery of saidplate, as shown at 35. Eachwedge-block is provided with an arm 36, whichextends along the outer face yof the'lifting-plate, and these arms areslidably connected to a Jfinger 37, which lies in the recess or groove32, so that movement of one of said'armscauses move ment of the otherthereof. A face-plate 38 is secured to the outer'face of thelifting-plate and is provided with a raised portion 39,which lies overthe arms 36, and thus produces a pocket for the same. The said arms areprovided with elongated-slots 40, which receive pivot-pins 41, securedin the lifting-plate and face-plate. The said wedge-blocks and the partsconnected thereto are so located upon the lifting-plate that they lie atthe upper portion of the said plate when the latter is in raisedposition. The wedge-blocks 34 thus fall by gravity into the recesses 33,and the finger 37 is raisedand projected beyond the periphery of thelifting-plate. As the liftingplate 'is turned the said finger engagesthe track and is forced inwardly, thereby forcing the `wedge-blocks outof their recesses, and the lifting-plate therefore slides over theforward wedge-block and causes the same to tightly wedge between therail and the pe? riphery of the said plate, there being sufcient play ofthe wedge blocks and between the arms 36 thereof to permit'such action.Manifestly as the lifting-plate is returned to normal position thewedge-blocks fall into their recesses, and the finger 37 is againprojected.

I shall now describe themeans for braking the wheel itself. Verticallyslidable in a suitable guide 42 -upon the lifting-plate is an arm 43,from whose'upper end a'brakeshoe 44 extends outwardly, said brake-shoelying above the tread of the wheel-and being preferably received in asuitable recess 45 in the inner face of the lifting-plate. Upon thelower end of the said arm 43 is an 'inwardly-extending finger 46, whoseupper surface tapers upwardly and outwardly, as shown, said fingerprojecting through a suitable slot 47 in the lifting-plate. Splined orotherwise slidably mounted upon the sleeve 18 is an outer sleeve 48,whichis pro IOC) vided near its inner end with a circumferential groove49. Slidably supported in the casing lO is a yokeV 50, whose arms havefingers 5l, which entervthe said groove, said yoke being ing-lever 26,the levers 54 in the various cars being preferably connected by means ofa cord 55. Thus rocking of the shaft 53 causes the sleeve 48 to be movedlongitudinally upon the sleeve 18.

The outer end -of the sleeve 48 is provided 'with a concentric recess56, whose encircling wall 57 has its inner face tapering outwardly andupwardly, and about said wall isa rim 58, which is eccentric to theinner face of the wall 57. Thus when the sleeve 48 is moved outwardlythe yrim 58 extends over the finger 46, and as the vsleeve rotates withthe shaft the wider portion'of the rim 58 moves over the said finger andthe brake-shoe is and as soon as the sleeve 48 is movedinto normalposition the wheel is relievedr from pressure, a suitable spring 59,between the arm 43 and the hub of the lifting-plate, serving to raisethe said brake-shoe.

Manifestly shafts 27 and 53 upon the vari-` ous cars can be connected inmany ways, and I have here shown each shaft as providedA at its endswith a well-known type of socket adapted to receive alcoupling-link.

In order toipreserve proper relationship betwe'en each shaft 27 and 53and the trucksupported parts connected thereto and'at the same time topermit the required swinging of the trucks, each shaft is made insections, which are connected by universal joints 60, and the sections6l and 62, whichv carry the roch-arms, are mounted upon the respectivetrucks to move therewith. An intermediate section 63 lies between thetruck-carriedsections 6l and 62,`and a coupling-section 64 is connectedto the outer end of each of said truck-carried sections.

I am aware that many minor changes Ain the construction, arrangement,and combination ofv the several parts of my device can be made andsubstituted forv those vherein shown' and described without in the leastdeparting' from the nature and principle of my invention.
